I've got to say, Siri on iOS 7 (GM, not beta) is really blowing me away. So long as I have a stable connection, it responds almost instantly, and it really does just work. I don't know what Apple's done, but it definitely deserves a round of applause. I've been using Siri for a long time, but even I had to admit its short comings now and then. Now, though, it just feels really rock solid and reliable!
